HOT SELL PRODUCT Our contact PRODUCT DESCRIPTION The drive axle is generally composed of a main reducer, a differential, a wheel transmission device, and a drive axle housing. Its function is to fold the power transmitted by the universal transmission device through a 90° angle, change the direction of force transmission, and reduce the speed by the main reducer, increase the torque, and distribute it to the left and right half shafts and the drive through the differential Wheel The drive axle is at the end of the power train. Its basic function is: ①Transmit the engine torque from the universal transmission to the drive wheels through the main reducer, differential, and half shaft, so as to reduce the speed and increase the torque. ②The transmission direction of torque is changed through the conical gear pair of the final reducer; ③The differential effect of the wheels on both sides is realized through the differential to ensure that the inner and outer wheels turn at different speeds; ④The bearing and transmission are realized through the axle housing and the wheels. Force actionThe ZL30 drive axle has a two-stage reduction structure, which is widely suitable for loading capacity On 1.5 cubic meters of wheel loaders and wheeled construction machinery with similar conditions, It has the advantages of reasonable design structure,reliable performance and long life. Adopt caliper disc brake, hydraulic braking, large braking torque, stable and reliable braking. The drive axle is divided into front and rear. The main difference lies in the main drive gear pair. The spiral bevel gears have different directions of rotation, and the drive axle has a variety of connection sizes to meet the different requirements of users. Working principle of drive axle assembly The power torque of the main engine is transmitted from the drive axle via the drive shaft. Then, change the direction of rotation to drive the passive spiral coneThe gears and the differential case rotate, the differential case belt The moving cross shaft and planetary gears transmit power to the half Shaft gears, half shaft gears transfer power through the half shaft Split to the wheel deceleration device on both sides, and then pass the wheel After the edge planet slows down, the power is finally transmitted to the planet Wheel frame, thereby driving the wheels to roll forward. That The transmission route is as follows Main engine power torque—input flange—main reduction Speed gear—differential gear—half shaft Wheel Reducer—wheel the structure and working principle of brake 1. Brake The brake is a hydraulic caliper disc brake, which has the characteristics of large braking torque and stable and reliable braking. Brake by inner caliper It consists of a body, an outer caliper body, a piston, a brake pad, and a brake benefit. The brake disc is fixed with the wheel hub and rotates relative to the axle housing shaft tube together, and the brake is fixed on the drive axle housing. The brake pad is connected with the inner and outer caliper bodies through a pin, and can move axially along the pin. 2. Working principle: When braking, the high-pressure brake fluid enters the hydraulic chamber behind the body from the brake pipeline through the caliper body oil port, driving both sides To achieve the purpose of braking. At the same time, the rectangular sealing ring produces elastic deformation under the action of friction. When the brake is released, the high-pressure oil is discharged, and the piston returns to the position by the elastic restoring force of the sealing ring. When the brake is released, the brake gap changes due to the wear of the friction lining. When braking, the piston overcomes the frictional resistance of the sealing circumference under the action of the pressure oil and continues to move outwards until the friction plate is pressed against the brake disc to be positive. When the brake is released, the elastic deformation of the sub-sealing ring is different, so the distance that the piston is pulled back by the sealing ring is naturally different from before it is worn, so the brake gap can be automatically adjusted. Working route: The hydraulic force of the cylinder-the piston moves-pushes the brake pad to clamp the brake disc 3. The brake fluid adopts Meihu D0T3 or 719 synthetic brake fluid, which cannot be mixed Maintenance and maintenance
